Earth Warming Faster Than Expected

Posted by ChevScience on June 5, 2012

By 2050, global average temperature could be between 1.4°C and 3°C warmer than it was just a couple of decades ago, according to a new study that seeks to address the largest sources of uncertainty in current climate models. That’s substantially higher than estimates produced by other climate analyses, suggesting that Earth’s climate could warm much more quickly than previously thought.

Many factors affect global and regional climate, including planet-warming “greenhouse” gases, solar activity, light-scattering atmospheric pollutants, and heat transfer among the land, sea, and air, to name just a few. There are so many influences to consider that it makes determining the effect of any one factor—despite years and sometimes decades of measurements—difficult. Learn more here.
